Filed: 2004-01-26
Abstract: An apparatus for and method of obstructing an air intake flow (115) improves the mixing and driving force when an EGR flow (111) is introduced to the air intake flow (115). Before the EGR flow (111) enters a passage (113) where it is intended to be mixed with an air flow (115), the air flow (115) is obstructed to enable better and faster mixing of the EGR flow (111) with the air flow (115). A pressure differential is created to increase suction of EGR  flow (111) into the intake air flow (115), thereby resulting in increased EGR  flow (111) into the cylinders of an engine.

Title: Methods of fabricating interferometric modulators by selectively removing a material
Inventor: CUMMINGS WILLIAM J
IPC: G02B26/00
Filed: 2005-09-21
Abstract: Methods for making MEMS devices such as interferometric modulators involve selectively removing a sacrificial portion of a material to form an internal cavity, leaving behind a remaining portion of the material to form a post structure.
